If there was a fight, and Android won, ChromeOS would just be abandoned. ChromeOS being folded into Andorid means that ChromeOS's time as a separate project to try things without disturbing the already phenomenally successful Android (and without being constrained by it) has run its course, and its time to apply ChromeOS lessons to Google's flagship client OS.

At this point, Android is about to win the fight of "client" operating system, overall. It definitely looks like the underdog in the Innovator's Dilemma (https://en.wikipedia.org/wiki/The_Innovator's_Dilemma).

Of course, why use a browser pretending to be an OS, when one can have a full OS that has lots of browsers to choose from?!

I said that on purpose and maintain my statement.

That was nothing more than the Chrome team playing at building OSes.

Android has much better brand appeal than ChromeOS
